To all whom it may concern.'

Be it known that I, ROBERT M. DowNI'n, a citizen of the United States,` residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented a new and useull Compressed-Air Water-Elevator, of which the following is a specification. l

This invention rela'tes more particularly to means for elevating water or other liquid by means of fluid under pressure, as for instance, com ressed air.

T e primary object of the resent invention is to rovide novel, simp e and effective means of t eV above character, said means insuring the delive of a proper proportion vof air or motive ui with the column of Water or liquid, and moreover being substantially automatic in its nature, so that as long as motive fluid is turned into the elevating means and there is a supply of liquid, the latter will be elevated.

The referred embodiment of the invention is ustrated in the accompanying drawin wherein:

i re 1 is a vertical sectional view through a weit1 showin the elevating means therein, portions of sai elevating means being shown 1n section. Fi 2 is a vertical sectional view through the e evating means. Fig. 3 is a cross sectional view on the line 3-3'of Fig. 1". Fig 4 is a cross sectional view on the line 4 4 of( ig. 1. Fig; 5 is a cross sectional'view on the line 5-5 of Fig.' 1. Fig. 6 is adetail sectional view on an enlarged scale of the upper head of the pump barrel. Fig. 7 is a p an view of the same. Fig. 8 is a top lan-view of the lower head of the pum barrel).

Similar reference numer designate' corresponding part's in all the figures of the awings.

The structure herein disclosed is shown in awell 9 having a suitable curb 10, which is covered with a ca 11. The particular character of the well, 1s however, not important. The mechanism consists of a barrel that comprises a cylinder 12, into the upper and-lower ends of which are threaded heads 13 and 14. The lower head 14 has a central inlet open'- ing 15 controlled by an inwardly opening valve' 16 having a stem 17'slidable in a web 18 that extends across the' inlet opening', afs' `.the lower portion o shown in Fig. 8. The upper head 131i`s "ro:

vided with two openings 19 and 20, w "ch maybe of different diameters. A 1i reid @nducting-pipe 21 liassec'tions three; edinto the opening 19, the' Vlower section 21"l exs tending of the pump barrel, and being of coiisideif` ably less diameter` than the same. The said liquid conducting pipe" extends through the cas' 11, and is connected by a couplinV 22to a elivelX pipe 23 extendin to any esired point. motive uid supp y pipe' 24 leadfy ing from any suitable source of supply, as for instance, anj-a'ir compressor, extends downwardly through the cap 11 into the well 9' alon side the conducting pipe 21. This mof tive uid supply pi e also as sections, which are threade mto t eopening 20 of theupper cap, and the lowersection 24 extends' down'- wardly within the barrel alongside the sec' tio'n 21a of the conduct' pipe'. It will thus be evident,` particularly y reference to Fig. 2 that the lower discharge end of the motive fluid supply pi e communicates with the' downwardlv into the lower portion lower portion o the' chamber or barrel, a'n'd in like dnanner, the lower inlet endv of the;

liquid conducting i e' communicates with fllzlge chamber or barrel di rectlyT contiguous to the discharge en'd of the' motive fluid supplypipe. These ends are connected-by a cou ling' 25, the lower' ends of the section 21 a of t e conducting pipe being.' threaded into said cou ling, the owe'r end 24a of the motive' flui'dpsupplypipe section' being loosel en .aged in anopening' in' said coupling. he ower portion of this coupL ling is cupped', as shown at 26, forming a' channel w1t an open bottom, and it will' be evident by reference to Fig. 2'that both pipes" communicate with this" channel. The cou g is of less cross sectional areathan t e barrel cylinder 12.-.

In the upper portion of the'section 2'1'a of the liguid conducting pipe is a vent 27 con'- stitutmg means of communication between the interior of the pipe and the up er portion ofthe pump barrel or chamber. irect c'In-' munica'tion is also established; between the motive' fluid supply pipe and the con"- ducting pi'pe atthe' upper end of t pump" barrel. or this purpose, a by- 4`asis"conduit' 28 is threaded into an opening 2 folmedbetween the oplegiings Alegend 20 in head, ar'i'd t conduit, whichhas one rijd'j ums in-.cemmunieatin with uiemfive eine ioo mitted to thefpipe 24, the same will flow' downwardl into the barrel. A portion of4 this air or uid will be directed by the lowerv 25 into the inlet channel 26 of the coupling endof the cenducting pipe, while another portion underiiowing the cou ling 25 rises through the water in the barre to the top of said barrel. This latter air will gradually displace the water in the barrel, forc` the level ower and lower, and as the only exit 1s through cupped end of the coup the liquid conducting pipez a column of water aerated by the air directed mto the pipe by the channel 26-will be elevated through the pipe 2 1 to the point of discharge. Thls current of water passing into the pipe will tend to carry more and more of the au' inwith it, and the will tend to harbor the air at the o ening so t at a pro er proportion of the air will be carried upwar y with the water. The air thus rising in the liquid conducting pipe will expand more and more, as it rises to oints where the pressure is lower. In time, t e accumulation of air under pressure in the barrel will overcome the hydrostatic pressure in the liquid conducting pipe and conse uently the barrel or chamber will be emptie through the same. Simultaneously with this emptying action, the air ressure 4which has `been accumulating, be reduced to substantially atmoplheric pressure, inasmuch as the a1r can e 'aust freely through the larger liquid conducting pip?. At this instant of time, the ressure o t e waterin the well will lift the ower valve and rush into the cylinder, iilling it almost instantly nearly to the top; inasmuch as the vent 27 will allow the escape of the air. A portion of the inrushing water will at the same time rise in the section 212 of the liquid conducting pi e,and as soon as the vent 27 is closed, the ower valve will also close because of the increasing pressure of air in the barrel. The above described action will then be again repeated. The use of the bypass is im ortant, inasmuch as it assists in relieving t e air ressure from the barrel while the latter is and asv soon as the water rises to cover the vent, an upward suction takes place due to the upturned k,air jet of the byass so thatthe cylinder is soon em tiedo water.

rom the foregoing, it is thought that the construction, operation, and many advanages of the herein described invention will t be a parent to those skilled the art, without rther description, and 1t will be underceases stood' various changes in the size, shape,

proportion', and minor details of'construction, may be resorted tofwithout depart' from the. s irit or sacrificing any of the'iald vantages o the invention.
